WARNING
• Donotusemeanstoacceleratethedefrostingprocessortoclean,otherthanthoserecommendedbythe
manufacturer.
• Theappliancemustbestoredinaroomwithoutcontinuouslyoperatingignitionsources(forexample:openames,an
operatinggasapplianceoranoperatingelectricheater).
• Donotpierceorburn.
• Beawarethatrefrigerantsmaynotcontainanodour.

5. Reattach the air lter. Page 8
6. Reattach the suction grille.
•RefertoSTEP2.
7. Close the suction grille.
•RefertoSTEP1.
Prior to a long period of non-use
1. Operate the FAN mode for
several hours to dry out the
inside.
•Tostarttheoperation,refertotheoperationmanual
fortheremotecontroller.
2. After operation stops, turn
off the circuit breaker for
the room air conditioner.
3. Clean the air lter and
reattach it.
4. To prevent battery leakage,
take out the batteries from
the remote controller.
(Only for the wireless
remote controller)
We recommend periodical
maintenance
•Incertainoperatingconditions,theinsideoftheair
conditionermaygetfoulafterseveralseasonsofuse,
resultinginpoorperformance.Itisrecommendedto
haveperiodicalmaintenancebyaqualiedcontractor.
•Forqualiedcontractormaintenance,pleasecontactthe
dealerwhereyouboughttheairconditioner.

When the Need Arises
Beforemakinganinquiryorarequestforrepair,pleasecheckthefollowing.
Iftheproblempersists,consultyourdealer.
Not a problem
Thiscaseisnotaproblem.
Check
Pleasecheckagainbeforerequesting
repairs.
Case Description / what to check
Operation does not start soon.
•
WhenON/OFFbuttonwaspressed
soonafteroperationwasstopped.
•Whenthemodewasreselected.
• Thisistoprotecttheairconditioner.
Youshouldwaitforabout3minutes.
Air does not come out.
In HEAT operation
• Theairconditioneriswarmingup.Waitforabout1to4minutes.
• Duringdefrostingoperation,hotairdoesnotowoutoftheindoorunit.
When the air conditioner operates immediately after the circuit breaker is turned on
• Theairconditionerispreparingtooperate.Waitforabout3to20minutes.
The heating operation stops suddenly
and a owing sound is heard.
• Thesystemistakingawaythefrostontheoutdoorunit.
Youshouldwaitforabout4to12minutes.
The outdoor unit emits water or
steam.
InHEATmode
• Thefrostontheoutdoorunitmeltsintowaterorsteamwhentheairconditionerisin
defrostoperation.
InCOOLorDRYmode
• Moistureintheaircondensesintowateronthecoolsurfaceofoutdoorunitpipinganddrips.
Mist comes out of the indoor unit. Thishappenswhentheairintheroomiscooledintomistbythecoldairowduringcooling
operation.
The indoor unit gives out odour.
Thishappenswhensmellsoftheroom,furniture,orcigarettesareabsorbedintotheunit
anddischargedwiththeairow.
(Ifthishappens,werecommendyoutohavetheindoorunitwashedbyatechnician.
Consulttheserviceshopwhereyouboughttheairconditioner.)
The outdoor fan rotates while the
air conditioner is not in operation.
Afteroperationisstopped:
• Theoutdoorfancontinuesrotatingforanother30secondsforsystemprotection.
Whiletheairconditionerisnotinoperation:
• Whentheoutdoortemperatureisveryhigh,theoutdoorfanstartsrotatingforsystemprotection.
The operation stopped suddenly.
(OPERATION lamp is on.)
 Forsystemprotection,theairconditionermaystopoperatingonasuddenlargevoltageuctuation.
Itautomaticallyresumesoperationinabout3minutes.
The air conditioner does not
operate.
(OPERATION lamp is off.)
• Hasn’tabreakerturnedOFForafuseblown?
• Isn’titapowerfailure?
• Arebatteriessetintheremotecontroller?
• Isthetimersettingcorrect?
Cooling (Heating) effect is poor.
• Aretheairltersclean?
• Isthereanythingblockingtheairinletortheoutletoftheindoorandtheoutdoorunits?
• Isthetemperaturesettingappropriate?
• Arethewindowsanddoorsclosed?
• Aretheairowrateandtheairdirectionsetappropriately?
Operation stops suddenly.
(OPERATION lamp ashes.)
• Aretheairltersclean?
• Isthereanythingblockingtheairinletortheoutletoftheindoorandtheoutdoorunits?
CleantheairltersortakeallobstaclesawayandturnthebreakerOFF.ThenturnitON
againandtryoperatingtheairconditionerwiththeremotecontroller.Ifthelampstillblinks,
calltheserviceshopwhereyouboughttheairconditioner.
• Areoperationmodesallthesameforindoorunitsconnectedtooutdoorunitsinthemulti system?
Ifnot,setallindoorunitstothesameoperationmodeandconrmthatthelampsblink.
Moreover,whentheoperationmodeisin“AUTO”,setallindoorunitoperationmodesto
“COOL”or“HEAT”foramomentandcheckagainthatthelampsarenormal.
Ifthelampsstopblinkingaftertheabovesteps,thereisnomalfunction.

If one of the following symptoms takes place, call your dealer immediately.
• The power cord is abnormally hot or damaged.
• An abnormal sound is heard during operation.
• The circuit breaker, a fuse, or the earth leakage circuit
breaker cuts off the operation frequently.
• A switch or a button often fails to work properly.
• There is a burning smell.
• Water leaks from the indoor unit.
Turnoffthecircuitbreakerandcallyourdealer.
After a power failure
•Theairconditionerautomaticallyresumesoperationinabout3minutes.Youshouldjustwaitforawhile.
Lightning
•Ifthereisarisklightningcouldstrikeintheneighbourhood,stopoperationandturnoffthecircuitbreakertoprotectthe

1. SAFETY PRECAUTIONS
•Keepthismanualwheretheusercaneasilyndit.
•TheprecautionsdescribedhereinareclassiedasWARNINGandCAUTION.Theybothcontain
important information regarding safety. Be sure to observe all precautions without fail.
WARNING CAUTION
Failure to follow these instructions properly may result
in personal injury or loss of life.
Failure to follow these instructions properly may result in
property damage or personal injury, which may be
serious depending on the circumstances.
Never attempt. Be sure to follow the
instructions.
Be sure to establish an
earth connection.
•After reading, keep this manual in a convenient place so that you can refer to it whenever necessary. If
the equipment is transferred to a new user, be sure also to hand over the manual.
WARNING
•Do not use means to accelerate the defrosting process or to clean, other than those recommended by the
manufacturer.
•The appliance must be stored in a room without continuously operating ignition sources (for example: open
ames,anoperatinggasapplianceoranoperatingelectricheater).
•Do not pierce or burn.
•Be aware that refrigerants may not contain an odour.
•Toavoidre,explosionorinjury,donotoperatetheunitwhenharmfulgases(e.g.ammableorcorrosive)
are detected near the unit.
•Be aware that prolonged, direct exposure to cool or warm air from the air conditioner, or to air that is too
cool or too warm, can be harmful to your physical condition and health.
•Donotplaceobjects,includingrods,yourngers,etc.,intheairinletoroutlet.Productdamageor
personal injury may result due to contact with the air conditioner’s high-speed fan blades.
•Do not attempt to repair, dismantle, reinstall or modify the air conditioner yourself as this may result in
waterleakage,electricshockorrehazards.
•Donotuseammablesprayneartheairconditioner,orotherwiseremayresult.
•Do not use a refrigerant other than the one indicated on the outdoor unit when installing, moving or
repairing. Using other refrigerants may cause trouble or damage to the unit, and personal injury.
•To avoid electric shock, do not operate with wet hands.
